ABSTRACT:
A low viscosity hydrocarbon solution of a dihydrocarbyl magnesium compound such as di(n-butyl) magnesium is provided by combining the dihydrocarbyl magnesium with a solubilizing amount of an organozinc or organoboron compound, a hydrocarbon liquid and a viscosity reducing agent such as an ether, alcohol, or an organo aluminum compound. Such solution is very useful in the preparation of high efficiency catalysts for the polymerization of ethylene and other alpha alkylenes at polymerization temperatures above 150.degree. C.
